WSS Bimetallic Thermometer with All Stainless Steel Build, No Power Needed, and Multiple Dial Sizes

Product Description

WSS Series Bimetallic Thermometer

The WSS Series represents the standard industrial model for bimetallic thermometers in China, widely exported globally for heating, boiler, pipeline, and process equipment temperature detection.

Product Overview

This mechanical temperature measuring instrument operates on the bimetallic strip thermal expansion principle, requiring no power supply, batteries, or wiring. The entire construction—including dial case and insertion stem—is crafted from stainless steel for superior rust and corrosion resistance. Available in various dial diameters, customizable probe lengths, and multiple temperature scales to suit diverse industrial applications.
